But the diplomatic efforts were unsuccessful, Obama said at a press conference on Monday.
Russian Federation and the USA have been striving for weeks to secure a ceasefire between Syrian President Bashar Assad's government and moderate rebels that would expand access for hundreds of thousands of civilians caught in the crossfire.
Significant sticking points remain in the negotiations over a creation of an unlikely U.S.
Russian and American experts have worked since July on details to halt the violence in areas where moderate opposition groups, supported by the United States and Gulf allies, and Russian-backed Syrian government forces have been battling.
In that regard Russian Federation is ready "to move forward as far as the British are prepared to go", Peskov said.
U.S. officials accused Russian Federation of backtracking on already agreed issues which Washington refused to revisit, but the talks seemed to have been overtaken by developments on the ground. The official, who wasn't authorized to discuss negotiations publicly and requested anonymity, didn't elaborate. Kerry and Lavrov had been working "around the clock" to come to an agreement, Obama told reporters. -Russian military partnership that Moscow has long sought. Stating that the fight against the Islamic State in Syria and Iraq is his first priority, Obama has been reluctant to directly involve the USA military in Syria's civil war, beyond providing limited arms and other assistance to moderate opposition forces.
While Carter's remarks followed hacking attacks on Democratic Party organizations in the lead-up to the November 8 USA election, his comments appeared to also reflect diverging policies in Syria.
But the U.S. has resisted coming to an agreement due to Russian and Syrian regime actions against civilians in the besieged, rebel-held city of Aleppo.
Obama on Sunday had tamped down expectations for a deal, saying negotiations with the Russians on a new cease-fire still had "grave differences" with what the US wanted. But officials removed Lavrov's podium just before Kerry came out - alone - to announce that no agreement had been finalized.
Turkey announced plans for a sovereign wealth fund last month, meant to boost annual growth over the next decade and reassure investors unnerved by a failed coup attempt in July. In his own news conference, Obama said he was skeptical that Russian Federation and Syria would abide by any agreement, but said a long-term solution to Syria's civil war is still urgently needed.
There was zero chance that Russian Federation would ground the Syrian air force and stop its bombing in exchange for what Kerry offered.
What Syria will look like when the conflict is over: Russia's involvement in the brutal and lengthy battle for Aleppo is thought to be driven by a desire to ensure that Assad and his regime are left with some sort of "rump state" to rule over once a peace deal is done.
Turkey-backed Syrian rebels would like to see a "safe zone" set up in areas of the border they are capturing from Islamic State, but this would need an agreement between the United States, Turkey and Russian Federation, a rebel commander said on Tuesday.
The offensive, led by an ultraconservative Islamic group, Jund al-Aqsa, and also involving several factions from the Western-backed Free Syrian Army, incurred an intense government bombing campaign that killed dozens of people.
Speaking in Oxford, England, on Wednesday, U.S. Defense Secretary Ash Carter accused Moscow of aggressive behavior aimed at eroding the global order. He says the US will take the time needed to ensure the agreement has the best chance for success. Lavrov's deputy, Sergei Ryabkov, said a deal was "close" but said Washington had to dissociate itself from Nusra.
